Your Computer
100% Private
Only a receipt number travels - like a ticket stub
Our Server
Can't read your chats
Watch how we protect your privacy...
Think of it like a photocopy machine in your office
The documents never leave the building. We just check that you have permission to use the machine - we never see what you're copying.
The Ultimate Privacy Test
We invite you to audit us yourself. Load the app, then disconnect your internet. You can process files of any size, generate PDFs, and save them—all while offline.
No connection, no transmission. Your data stays on your device—by design.

Built from the ground up to meet the strictest data protection requirements.
Data Sovereignty
GDPR Art. 44
Data never crosses borders. Because processing happens locally on your machine, your sensitive information remains physically within your jurisdiction at all times.
Zero Sub-Processors
GDPR Art. 28
We do not send your data to third-party cloud providers (like AWS or Google Cloud) for processing. The chain of custody remains strictly between you and your device.
Right to Erasure
GDPR Art. 17
Instant absolute deletion. Since we don't store your data, there are no server backups to purge. Simply close your browser tab, and the data is wiped from memory forever.
Encryption Standards
Industry Best Practice
All license verification traffic is encrypted via SSL/TLS 1.3. Your actual chat content is never transmitted, so it does not require network encryption.
How We Verify Without Seeing
Our purchase system uses cryptographic fingerprinting to verify your exports without ever accessing your file contents.
SHA-256 File Fingerprinting
When you export a file, we generate a unique SHA-256 hash (digital fingerprint) of your chat file directly on your device. This fingerprint is mathematically unique to your file, but reveals nothing about its contents.
This is all we ever see. Your messages, names, and media remain completely private.
Forensic Standard
SHA-256 is accepted in legal proceedings worldwide for file integrity verification.
Free Re-Exports
Already purchased a file? The fingerprint matches your receipt, so you can re-export anytime without spending another credit—including both Legal Transcript and WhatsApp bubble formats.
Works Offline
Your purchases are cached locally with AES-256 encryption, valid for 3 hours. Export anywhere, anytime.
File Loaded
Your chat file is loaded into browser memory (never uploaded)
Hash Generated
SHA-256 fingerprint is calculated locally on your device
Receipt Created
Only the hash is sent to create your purchase receipt
Cached Securely
Receipt is encrypted and stored locally for offline access
Where Does Your Data Go?
Understanding the difference between cloud processing and local processing is critical for compliance.
Standard Cloud Converters
You upload your private chats to a remote server. You have no control over who sees them, how long they are stored, or if they are hacked.
- Data transmitted to third-party servers
- Unknown data retention policies
- Potential breach exposure
- Chain of custody compromised
Print Chat Secure Engine
Our software runs entirely inside your browser's secure sandbox. The data never leaves your laptop's memory. No uploads. No cloud storage. No risk.
- 100% local processing
- Data wiped when tab closes
- Zero breach surface
- Chain of custody preserved
How Local Processing Works
A simple explanation of our privacy-first architecture.
You Select a File
Your WhatsApp export stays on your hard drive. We only read it temporarily into browser memory.
Processing Happens Locally
Our secure engine converts messages to PDF format entirely within your browser. Nothing is sent anywhere.
You Save the PDF
The finished PDF is saved directly to your computer. Close the tab and all temporary data is gone.
